AURA ～魔竜院光牙最後の闘い～

Ichirou Satou once called himself Koga Maryuin and acted out a hero's fantasy until classmates bullied him into burying that past. At a new school he tries to pass as ordinary, but then he meets Ryouko Satou, a girl in a blue cape who insists she is a researcher from another world hunting a 'Dragon Terminal'. Her behavior mirrors the chuunibyou phase he is desperate to forget. When he sees her being bullied, Ichirou chooses to play along and accept who he was.
